Mentimeter has a large user base (~50 Million), experiences continuously fast growth, but we are a long way from reaching our goal. This puts a lot of demands on the scalability and performance of the architecture of systems. As a Cloud DevOps Engineer at Mentimeter, you will continuously monitor any performance bottlenecks that might appear in business-critical services, and you will address these yourself or together with other engineers at Mentimeter.

You will manage and support the cloud infrastructure, and be a critical part of enabling all engineers in the Product Team to deliver quality code quickly by ensuring our continuous deployment pipeline is as streamlined as possible. To succeed in the role you should be curious about how to build and uphold a large-scale, business-critical system with modern technologies and your responsibilities will include the research, design and implementation of services that can scale in an efficient and reliable manner. It is important that you have a great interest for automating our cloud environments for security, reliability and scale, and build monitoring and observability solutions to ensure overall system health.

Mentimeter is a high transaction system built in React, Redux, Ruby, Node.JS with a PostgreSQL database for persistence, Redis for caching and queuing, AWS Redshift for Business Intelligence, CloudFront as a CDN (with Lambda@Edge), and WebSockets to enable a fast and interactive polling experience. Hosting is done on Heroku and AWS with Continuous Integration using Github and Circle CI. We also utilize GatsbyJS for our static content sites to be able to deliver a blazingly fast experience for our end users.

For many things we do at Mentimeter we always strive to automate and simplify, focusing on keeping our platform advanced enough to support our main use cases but at the same time keeping the complexity low to ensure a low maintenance cost. If there is an external provider or SaaS that provides a good solution we tend to choose that as opposed to building it ourselves in order for us to be able to focus on our core business and keep our development speed high. We expect you to share this vision and balance in your work reaching out to your fellow engineers when needed to take important decisions.

We are in an exciting phase where the platform must evolve in order to ensure continued scalability of the product and our business. You will help make decisions on which architecture and technologies are best suited for our future challenges. We are, for example, looking to build our own WebSocket infrastructure for better control and reliability (perhaps based on Go) and opening up a Public API which will enable the possibility of an ecosystem of new innovations based on Mentimeter technology.

We work in small, independent, self-organizing teams. The team’s Product Manager and Engineering Lead work together to organize and plan the team’s backlog with a Kanban/Scrum-mixed process, with a focus on continuously delivering new features to our users.


  • Balancing “do it yourself” vs “there is a SaaS for that” to find the smartest solution in line with business and product strategy
  • Continuously monitor any performance bottlenecks that might appear in business critical services
  • Suggest actions/changes to address these bottlenecks, be proactive and work with a high degree of autonomy
  • Suggest project that enable all engineers in the product team to deliver quality code fast by ensuring our continuous deployment pipeline is as fast as possible
  • Together with other Fullstack Engineers or by yourself implement features while ensuring the long-term stability of our system and the quality of the code
  • As a Cloud DevOps Engineer be able to take on initiatives and follow others’ requirements
  • Influence which tools, programming languages, and technologies you work with
  • Help ensure we have a smooth software pipeline for continuous and fast delivery
  • Balancing discovery phases with implementation work
  • Be excellent at working both independently and in a team
